Cleaning counter-electrodes and contact pieces:
1. Unscrew the lower pressure pieces and
remove the respective contact pieces (if
required, use pliers).
2. Use the brush included in the supply to clean
the counter-electrodes with the same
detergent. After cleaning, flush the counter-
electrodes with water.
3. After cleaning the counter-electrodes, the
contact pieces must also be cleaned. For this,
use the tooth brush.
Blow all the parts dry and re-install the analyser
block in the reverse order.
NOTE:
The inclined surface at the shaft of the measuring
and calibration electrode must not block the
aperture to the flowmeter or to the mixing spiral.
The surface where the electrodes and contact
pieces are connected must be dry.
